Magnetic H-Loop antennas 
There are three different magnetic antenna options: As the antenna diameter gets shorter, the spatial 
resolution increases at the cost of some sensitivity loss at low frequencies, but best response at high 
frequencies; you should select RFEAH-25 for best sensitivity with connectors, large ICs and isolated signal 
traces, whereas RFEAH-5 works best for very narrow selective work in a populated PCB with close-by signal 
traces. RFEAH-15 is a good in-between compromise. 
Stub E-Field antenna 
The electric field RFEAE-10 stub offers a 
remarkable spatial resolution to determine 
the exact component in the PCB causing a 
problem, no matter how small it is.  
You can easily determine signal level at the 
input and output of a filter, amplifier, 
mixer, etc in a tight SMD assembly as 
picture below.
